Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment 1: as shown in Figure 1-2, the foaming tube extrusion die of a kind of adjustable feed rate of the present invention, the cylindrical core mold 4 comprising laterally extending tubular mouth mould 2 and be located in mouthful mould, annular interstice between mouth mould 2 and core 4 becomes slurry channel 6, the axis of described core 4 is provided with laterally extending mandrel 8, axially middle part is provided with the columnar stays bar 10 of connecting mandrel 8 and mouth mould 2 outer wall, the two ends of extrusion die transverse direction are respectively arrival end 1 and the port of export 3, described arrival end 1 place, core 4 is provided with head and is taper and the adjuster 12 adjustable relative to the axial distance of core 4, described adjuster 12 is connected with core 4 by screw 14, head outwardly.Described entrance point 1 is provided with flange 16, for being connected with charging mould.Along described entrance point 1 to support bar 10 direction, the annular width of slurry channel 6 arbitrary section is vertically equal, and the internal radius of arbitrary section increases gradually.Along support bar 10 to the described port of export 3 direction, slurry channel 6 is divided into two sections, and be bordering on a section of support bar 10, the annular width of arbitrary section reduces gradually, and the internal radius of arbitrary section also reduces gradually; Be bordering on one section of the described port of export 3, the annular width of arbitrary section is equal, and the internal radius of arbitrary section is equal.The conical nose 121 of described adjuster 12 is arranged on cylindrical body 122, body 122 free end is adjuster 12 afterbody, described afterbody is provided with deep hole 18 vertically, one end that described core 4 is connected with adjuster 12 is link 41, link 41 is provided with the protrusion 20 that profile matches with described deep hole 18 interior shape, be provided with ring-shaped rubber pad 22 between the tail end face of adjuster 12 and the end face of core link 41, described protrusion 20 passes from ring-shaped rubber pad 22 center.Described screw 14 is positioned at the afterbody deep hole 18 of adjuster 12, and one end is fixed on bottom deep hole 18, the other end with core 4 protrudes 20 tops and is connected, and adjuster 12 and core 4 are coaxially arranged.Described deep hole 18 length is vertically less than screw 14 length and protrudes 20 length sums.
Embodiment 2(is not shown): be with the difference part of embodiment 1: described screw 14 is radial along core 4, the protrusion 20 of core 4 is provided with the screw 24 that 3-4 is in diverse location vertically, and described each screw 24 matches with described screw 14 respectively.During use, coordinate different screws 24 by screw 14 grafting, change the axial distance of adjuster 12 relative to charging mould outlet end 3.
When manufacturing foaming tube, the arrival end 1 of extrusion die is connected by flange with charging mould outlet end 5, adjuster 12 head 121 inserts in charging mould internal channel 7, because common internal channel 7 two ends are horn-like, therefore adjuster head 121 specifically inserts the horn-like position 9 that internal channel is bordering on charging mould outlet end 5.The distance of adjuster head 121 relative to inserted horn-like position 9 is changed by screw 14, namely the channel sized formed between the male cone (strobilus masculinus) of adjuster head 121 and the inner conical surface at described horn-like position 9 is also adjusted, is conducive to the flow controlling body slip in internal channel 7.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to right.
